kernel - Fix spin-based msgports
* LWKT threads can use thread/IPI or spin-based message ports. The
default is thread-based. Spin-based ports had numerous problems which
would result in panics. This commit fixes those panics and makes the
spinlock version viable.
* However, currently there is no performance improvement so the default
is staying as it was.
